Cerad, thanks for the quick response. Sorry, that was a contrived example to illustrate what I am doing and I unwittingly created a typo in it. My real code doesn't have the typo but I am seeing the displayField posted rather than the valueField.

Okay, this works fine for getting the 'key' for a key/value combo arrangement which is commonly required dealing with data stored in databases where data has been normalised using foreign keys, but how can I preload a form containing combo boxes in the scenario describe below? (Which, by the way, works fine as long as your form just has regular text fields.)

In my simple case I have a small grid to the left being used as a selection list, and when a row is selected, a form on the right is preloaded with data from the grid store:

, the field is showing the 'key' (ie id_title), rather than the 'value' (title).
I'm thinking I will have to add a line or two more code to dynamically correct the values set in the title and hiddenTitle fields something like this?

And you might run in to the case where the form is rendered before the store finishes loading. In that case you will have to hang a listener off of the store and trigger an update of the form.

Thanks again cerad, yes I had switched from local store to remote and forgot to update the mode. Now both combo boxes are showing the values that should go into their hidden fields after the form is loaded from the store record which is NOT what I want at all. See attached.

I tried the following to preset the title to the value that is in the grid store:
